Now Joe Perry reveals that Whitford suffered internal bleeding after smacking his head while getting out of his Ferrari roughly two weeks ago.

In an interview with Reuters, Perry said, "It built up pressure and gave him this whoopin' headache. He's not prone to getting migraines, so he knew something was wrong. He went right in, they did what they had to do, and now he's getting better."

Because Whitford's injury required immediate surgery, the band scrambled and quickly recruited guitarist Bobby Schneck to replace Whitford while he recovers.
